Hi looking for some advice, i am growing blue cheese and was using the full canna range but decided to give general hydroponics nova flora. I fed both with the canna aqua and everything was cool, then changed one of the plants to nova flora. That was 2 days ago and the plant looks as if its dying the other is fine. The ph is 5.7 and ec 1.4 in both tanks. Do you think changing my feed has done this or does anyone have any ideas. Ive emptied the tank and just running ph 5.5 water through it to try and save it. Heres a couple of pics they both looked the same until 2 days ago
